Abstract

L'invention concerne un aubage de stator présentant moins de possibilités de déformation thermique et de réduction de résistance, un degré accru de liberté de forme et une performance de compression améliorée. L'aubage immobile est muni de corps d'aube de stator (21) dont chacun comporte une aube de stator (27), une section de carénage interne (31) et une section de carénage externe (29). Les sections de carénage interne et externe (31, 29) sont des éléments fendus respectivement de façon à correspondre à l'aube de stator (27) et formées d'un seul tenant avec les extrémités opposées de l'aube de stator (27). L'aubage immobile est également munie d'une section de joint en forme d'arc circulaire (23) construite à partir d'éléments de type plaque en forme d'arc circulaire et placée sur au moins l'une ou l'autre des sections de carénage interne et externe (31, 29) de corps d'aube de stator périphériquement adjacents (21), de façon à être positionnée sur le côté opposé aux aubes de stator (27). Une partie de la longueur périphérique de chacun des corps d'aube de stator (21) est soudée à un élément de joint correspondant (23).
